Answer:

if(isalpha(passCode[0]))

{

passCode[0] = '_';

}

if(isalpha(passCode[1]))

{

passCode[1] = '_';

}

Explanation:

The first if statement uses isalpha() function which checks if the character passed in this function is an alphabet. If the character stored in 0-th position (which is the first position whose index is 0) of the variable passCode is an alphabet then it is replaced with the '_'

The next if statement checks if the second character in the passCode variable is an alphabet. This means the function isalpha() checks if the character stored in second position (index 1) of the variable passCode is an alphabet then it is replaced with the '_'

Write a function called sum_scores. It should take four arguments, where each argument is the team's score for that quarter. It

saw5 [17]

Answer:

Here is the Python program which has a function sum_scores:

def sum_scores(score1, score2, score3, score4):

sum = score1 + score2 + score3 + score4

print(sum)

sum_scores(14,7,3,0)

Explanation:

Method sum_scores takes four arguments, score1, score2, score3, score4.
The sum variable adds these four scores and stores the value of their addition.
Lastly print statement is used to print the value stored in sum variable which is the value obtained by adding the four scores.
Last statement calls the sum_scores method and passes four values to it which are 14,7,3,0
The output of the above program is:
24
If you want to use return statement instead of print statement you can replace print(sum) with return sum. But in order to display the sum of the scores you can replace sum_scores(14,7,3,0) with print(sum_scores(14,7,3,0))
The program along with the output is attached as a screenshot.

Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255

maxonik [38]

Answer:

Follows are the code to this question:

#include <iostream>//defining a header file

using namespace std; //using namespace

int main() //defining main method

{

int red,green,blue,s; //defining integer variable

cout<<"Enter value: \n ";//print message

cin>>red>>green>>blue; //input value

if(red<green && red<blue)//defining if block that checks red value

s=red;//store red variable value to s variable

else if(green<blue)//defining else if block that checks green value less then blue

s=green;//store green variable value in s variable

else//defining else block

s=blue; //store blue variable value in s variable

//calculating red, green, blue value

red=red-s;//store red value

green=green-s;//store green value

blue=blue-s;//store blue value

cout<<red<<" "<<green<<" "<<blue;

}

Output:

Enter value:

130

80 0 80

Explanation:

In the above code, inside the Main method, four integer variable "red, green, blue, and s" is defined, in which "red, green, and blue" is used for input the value from the user end.

In the next step, a conditional statement is used, that checks the red variable value, if the condition is true, it will store its value in the "s" variable, otherwise, it will go to else if block.
In this block, the green variable checks its value less than then blue variable value, if the condition is true, it will store the green value in the "s" variable, otherwise, it will goto else block.
In this block, it will store the blue variable value in the "s" variable, and subtract the value of "red, green, and blue" value from "s" and store its value, and at the last, it will print its value.

KATRIN_1 [288]

Paired programming:

Paired programming is a new technique where one person gets one another to write the code. Here one will write the code and other will start verifying as the type.

So we might think it is waste to employ two person for same task but it is not so. There are many benefits in incorporating this technique. Let us see those benefits one by one.

Inter-personal skill gets improved

Lower amount of coding mistake

Learn from each other

Peer review enhance collaboration

Challenges expect to arise during pair-programming

Two heads are superior to one. On the off chance that the driver experiences a hitch with the code, there will be two of them who'll take care of the issue.

Builds up your staff's relational aptitudes. Working together on a solitary venture encourages your group to welcome the estimation of correspondence and collaboration.

Overcome Method

The most ideal approach to move toward blending is to accomplice two software engineers and have them share a PC. The pair ought to have the option to choose how to part the work, and it is prudent that they should switch jobs frequently.
